Entity

Example

Example Entity class adalah kelas asas abstrak untuk objek yang boleh dilampirkan kepada sebuah Node dalam graf adegan Aspose.3D. Subkelas konkrit termasuk Mesh, Camera, Light, dan Geometry. Entity menyediakan akses kepada hierarki nod induk dan mendedahkan getExcluded() kaedah untuk kawalan kebolehlihatan.

import com.aspose.threed.Scene;
import com.aspose.threed.*;

Scene scene = Scene.fromFile("model.obj");

for (Node node : scene.getRootNode().getChildNodes()) {
    Entity entity = node.getEntity();
    if (entity != null) {
        if (!entity.getExcluded()) {
            Node parent = entity.getParentNode();
            System.out.println("Active entity '" + entity.getName()
                + "', parent: " + (parent != null ? parent.getName() : "None"));
        }
    }
}

Example

A3DObject -> SceneObject -> Entity

Subkelas: Geometry -> Mesh, Camera, Light, dan lain-lain.

Example

Entity adalah kelas asas abstrak dan tidak diinstansiasikan secara langsung. Gunakan subkelas konkrit seperti Mesh.

Example

Name	Type	Access	Description
`parentNode`	`Node`	Read	Gets the parent node.
`parentNodes`	`ArrayList<Node>`	Read	Gets the parent nodes.
`excluded`	`boolean`	Read	Gets the excluded.
`boundingBox`	`BoundingBox`	Read	Gets the bounding box.
`scene`	`Scene`	Read	Gets the scene.
`name`	`String`	Read	Gets the name.
`properties`	`PropertyCollection`	Read	Gets the properties.

Example

Signature	Description
`Entity()`	NURBS curve is a curve represented by NURBS(Non-uniform rational basis spline), A NURBS curve is defined by its getOrder(), a set of weighted Geometry.getControlPoints() and a getKnotVectors() The w component in control point is used as control point’s weight, whatever it is a CurveDimension.TWO_DIMENSIONAL or CurveDimension.THREE_DIMENSIONAL
`Entity(name: String)`	Creates a new Entity with the given name
`getParentNode()` → `Node`	Constructor of instance.
`setParentNode(value: Node)`	The Boolean operator used in the operation to create the result mesh.
`getParentNodes()` → `ArrayList<Node>`	Protected constructor to allow derived classes to set name.
`getExcluded()` → `boolean`	The Boolean operator used in the operation to create the result mesh.
`setExcluded(value: boolean)`	Sets the excluded value.
`getBoundingBox()` → `BoundingBox`	The first operand of the Boolean operator.
`SceneObject()`	Boolean operator allows you to apply Boolean operation on two IMeshConvertible instances.
`getScene()` → `Scene`	Constructor of BooleanOperator.
`A3DObject()`	Parameterized Cylinder. It can also be used to represent a cone when one of radiusTop/radiusBottom is zero.
`getName()` → `String`	The segments of the curve.
`setName(name: String)`	Constructs a CircleShape profile with specified radius.
`getProperties()` → `PropertyCollection`	Initializes a new instance of Cylinder class.
`findProperty(name: String)` → `Property`	Initializes a new instance of the Bone class.
`getProperty(name: String)` → `Object`	Gets the transform matrix of the node in current pose.
`setProperty(name: String, value: Object)`	Gets the width segments.
`removeProperty(name: String)` → `boolean`	Gets flip coordinate system of control points/normal during importing/exporting.

Example

Periksa keadaan entiti selepas memuatkan adegan:

import com.aspose.threed.Scene;
import com.aspose.threed.Node;
import com.aspose.threed.Entity;
import com.aspose.threed.*;

Scene scene = Scene.fromFile("model.stl");

for (Node node : scene.getRootNode().getChildNodes()) {
    Entity entity = node.getEntity();
    if (entity == null) continue;

    System.out.println("Entity: " + (entity.getName().isEmpty() ? "(unnamed)" : entity.getName()));
    System.out.println("  Type: " + entity.getClass().getSimpleName());
    System.out.println("  Excluded: " + entity.getExcluded());
    System.out.println("  Parent node: "
        + (entity.getParentNode() != null ? entity.getParentNode().getName() : "None"));

    if (entity instanceof Mesh) {
        Mesh mesh = (Mesh) entity;
        System.out.println("  Vertices: " + mesh.getControlPoints().size());
        System.out.println("  Polygons: " + mesh.getPolygonCount());
    }
}
